Description

[0001] The present invention relates to a waste recycling plastic sorting system,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste plastic recycling plastic sorting and sorting system, and more particularly, to a waste plastic recycling plastic sorting and sorting system for classifying and discharging used plastics by materials.

In general, recyclable wastes such as beverage cans, bottles, or various kinds of packaging materials from households or factories are divided into the same group (s), and resources are secured through reprocessing. It is well known that there is an effect of preventing environmental pollution caused by waste.

In addition, when waste is discarded at a home or factory, it is separated from those that can be recycled and those that are not. In addition, recyclable wastes that can be recycled are collected through separate collecting operations, and then collected in the same group, such as metal materials, paper materials, glass bottles, And recycled raw materials are sent to a recycling factory to be recycled as resources.

Conventionally, referring to this, collecting, collecting and collecting various kinds of recycled wastes, transporting light and heavy materials through the conveying means, and recycling waste sorting process of separating the raw materials among the light and heavy materials transferred after the collecting process .

In addition, the collecting process collects the recycled waste collected from a home or a factory, separates the waste into a large water, a heavy material and a light material by hand, and the heavy, heavy and light water is transferred to the sorting process through the conveyer means, Lt; / RTI >

Here, the criteria for large water, heavy, and lightweight water are that recycled wastes, such as refrigerators, that are combined with other materials of different volume or different types, are separated into large water, and recycled wastes of small volume or single material, such as bottles, It is separated into water.

Also, the sorting process is to sort the recycled wastes of the transported heavy and light-weight materials by the respective raw materials, that is, the metals, the paper and the plastics after the collecting process. In this case, the metals are separated using the magnetic separator using the electromagnet, Wind turbine screening device, Trommel screen and non-ferrous metal separator.

In addition, each of the recycled wastes sorted according to the material is compressed to a predetermined size through a compressor or a crusher, and transferred to a recycling plant for each material.

Here, metals and paper are visually distinguishable, and in the case of metals, they are easily separated because they can be distinguished from each other by material selection and visual inspection through a metal separator or a non-metal separator.

However, in the case of plastic, it is separated into a synthetic resin by the naked eye, and it is difficult to select the precise material of a product made of a synthetic resin, and if the selection is made only by the naked eye, There arises a problem in that it can not be recycled due to mixing of different synthetic resin materials.
